What is a piping hydrostatic pressure test?

A hydrostatic pressure test may be carried out on pressure vessels such as industrial pipelines, plumbing and gas cylinders.


The vessels are tested for strength and to check for any leaks. Leaks are detected by filling the vessel or pipe with liquid and applying the specified test pressure, this will allow for leak detection. If the water is dyed with a colourant it is easier to detect.

Carrying out regular pressure tests will help maintain safety, durability and prevent further damage.
